On top of that, even the "warm" color temperature LEDs put out a pretty good spike of blue light. I'm working on some analysis of this, and even the "warm glow" sort... yeah, there's a ton of blue. Right in the realm of spectrum that convinces our body it's day.

So I'm not sure that the whole color shifting makes a big difference if you don't get rid of the blue as well. White LEDs are generally blue LEDs with phosphor coatings, but they still leak the blue. It's quite annoying.

I've been going back to incandescents and they're properly nice in the evenings.
